I guess the entire Federal Gov't would be classified as crazy since they tell us to be "preppers". The Federal Gov't tells us to prepare for a disaster, either natural or man made through their own Federal website. They tell you to prepare for evacuation rendezvous points and excess emergency supplies that can last you months.
All over the world past and present, both man made and natural disasters strike routinely. Yet people who wish to prepare and protect their families from things like supply shortages and even looters are characterized as crazy. The ones who think they're crazy should have sat out on a front stoop in Staten Island in the aftermath of Hurricane Sandy and seen how long they lasted without a weapon to defend themselves at night. FEMA and law enforcement were no place to be found.
